Authorizations
App key issued from the Flashduty console under Account → APP Keys. Required on every public API call. Keep it secret — it grants the same access as the owning account.
Body
Filter parameters for listing outbound webhook delivery history. The query is bounded by a required millisecond time window; use search_after_ctx for cursor-based pagination.
Page size.
1 <= x <= 100Window start time in Unix milliseconds.
1000000000000 <= x <= 9999999999999Window end time in Unix milliseconds. Must be greater than start_time.
1000000000000 <= x <= 9999999999999Opaque cursor returned by a previous call for fetching the next page.
Ascending order by event_time when true; otherwise descending.
Sort field. Currently only event_time is supported.
event_time Reference ID filter (incident or alert ID).
128Filter by integration ID.
x >= 0Filter by event type values.
Filter by delivery status.
success, failed Response
Success
Success response envelope. On every 2xx response, request_id identifies the call (also mirrored in the Flashcat-Request-Id header) and data holds the endpoint-specific payload. Failure responses use a different shape — see ErrorResponse.
